Abstract: The coherent optical Raman oscillator disclosed employs a semiconducting crystal having simultaneously Raman-active and infrared-active phonons. The oscillator has an optical resonator for the scattered light and is end pumped with intense coherent circularly polarized light. The oscillator is tuned by controlling the charge carrier concentration pertinent to the scattering by injected carriers and by a variable magnetic field directed along the resonator axis. This magnetic field may vary through both polarities to provide the full tuning range.

Abstract: A coherent optical Raman oscillator employing a semiconducting crystal having simultaneously Raman active and infrared-active phonons is disclosed in which mixed excitations called polaritons or plasmaritons scatter light substantially in the forward direction and in which the scattered light is resonated along an axis substantially collinear with the pump propogation and simultaneously is tuned by changing the carrier concentration or an applied magnetic field to maintain the required phase-matching to the pump and the mixed excitation. Carrier concentration can be changed by two-photon absorption or current injection.
